Production of a Scalar Boson and a Heavy Fermion Pair in Counterpropagating Е–Е+ Beams

The process of production of an HSM scalar boson of the Standard Model (H and h bosons of the Minimal Supersymmetric Standard Model) and a heavy fermion pair t t ¯ in counterpropagating electron-positron beams e − e + ⇒ H SM t t ¯ e − e + ⇒ Ht t ¯ e − e + ⇒ ht t ¯ ) is discussed. Analytical expressions for the energy spectrum of the Higgs boson and the transverse spin asymmetry and the right-left spin asymmetry are obtained, and their dependences on the emission angle and energy of the Higgs boson are investigated.
